Electooptical Communications and Power Cable

An electrooptical communications and power cable has at least one light waveguide, which is arranged in a central multifibre bundle consisting of a smooth flexible metal tube and provided with a primary jacket. Two layers of stranded metal wires are extended coaxially to the multifibre bundle. The metal wires are also used for relieving a traction and / or transversal load. The internal metal wire layer consists of metal wires exhibiting a good electric conductivity. The external metal wire layer has metal wires which are arranged alternately individually and / or group groupwisely and exhibit a good electrical conductivity and metal wires exhibiting a high traction strength. The two wire layers are held at a distance (a) from each other by an insulating layer. The communications and power cable is used first of all for an electrooptical power connection between two voltage converters in an intelligent system.

Hybrid electro-optic cable

InactiveUS20020126967A1Reduce initial system cost costReduce cost ongoing maintenance costCommunication cablesFlat/ribbon cablesElectricityFiber
A hybrid cable comprising an optical fiber, an intermediate layer surrounding the optical fiber, and an electrically insulating jacket surrounding the intermediate layer. The intermediate layers include a collection of metallic strands. The hybrid cable may be used to establish simultaneous electrical and fiber-optic connection between two communication devices. Thus, the two communication devices may simultaneously transfer optical signals through the optical fiber and perform any of various electrical functions (power transfer, eye safety control) through the metallic strands. For example, an optical transceiver may couple to an optical antenna unit through the hybrid cable. Such an optical transceiver may serve as part of a point-to-point link, a point-to-multipoint link, and / or, a link between a primary transceiver unit and an optical router.

According to one embodiment, a deformable elastomeric conductor is configured to transmit electrical signals. It comprises: an elastomeric polymer matrix; and conductive filler material uniformly dispersed in the elastomeric polymer matrix sufficient to render the material electrically conductive. The conductive filler material may include substantially non-entangled particles having an aspect ratio sufficiently large to enable the particles to substantially remain in contact and / or in close proximity with adjacent particles so as to maintain conductive pathways in the material when the material is subjected to deformation up to and exceeding 10% strain. Thus, over a transmission distance of an electrical signal through the conductor, the transmission does not suffer greater than about 3 dB of signal attenuation when subjected to the deformation.
